A lifting cylinder 25 is fixed to the center of the top surface of the gripping connecting plate 24 (the lifting cylinder 25 is connected to the pneumatic system via a connecting pipe, and the lifting and lowering of the push rod of the lifting cylinder 25 is controlled by the control valve of the pneumatic system; this is a conventional structure and will not be described in detail here). The bottom end of the push rod of the lifting cylinder 25 extends out of the bottom surface of the gripping connecting plate 24 and is fixed to a gripping lifting plate 26. Multiple vacuum suction cups 200 are fixed to the left and right sides of the bottom surface of the gripping lifting plate 26. All vacuum suction cups 200 are connected to the control valve of the vacuum pump via a connecting pipe; the suction and closing of the vacuum suction cups 200 are achieved by opening and closing the control valve. A dual-station CNC hot press is installed at the rear of the main frame 10, and all vacuum suction cups 200 correspond to the placement grooves on their heating placement plates. The dual-station CNC hot press, vacuum pump, control valve, and other components are all conventional structures and will not be described in detail here.

[0017] Furthermore, a feeding rack 30 is fixed on the ground on the left side of the main frame 10. A placement block 31 is fixed in the middle of the top surface of the top plate of the feeding rack 30. The top surface of the placement block 31 is formed with two corresponding feeding grooves 32. The workpiece 100 to be processed is placed in the corresponding feeding groove 32, and its outer side wall is in close contact with or close to the inner side wall of the feeding groove 32 (with a distance of 1 to 2 mm between it and the inner side wall).

[0018] Furthermore, a workpiece conveying frame 40 is fixed on the ground on the right side of the main frame 10, and the gripping lifting plate 26 corresponds to the workpiece conveying frame 40.

[0019] Furthermore, the forward and backward moving mechanism 20 includes front and rear end fixing plates 28 fixed to the top surface of the horizontal fixing plate 12. The two ends of the forward and backward extending moving screw 29 are movably connected to the two end fixing plates 28 through bearings.

The output shaft of the moving motor 281 is a spline shaft, which is inserted into the spline hole at one end of the corresponding moving screw 29 and drives the moving screw 29 to rotate. The moving block 21 is screwed onto the moving screw 29.

[0020] Furthermore, a support guide block 50 is fixed to the horizontal fixing plate 12 on the left side wall of the rear end fixing plate 28. A guide groove 51 is formed in the center of the top surface of the support guide block 50. The extension rod 22 is inserted into the guide groove 51. A self-lubricating layer 52 is fixed to the inner side wall and bottom surface of the guide groove 51. The bottom surface and left and right side walls of the extension rod 22 are in close contact with the corresponding self-lubricating layer 52.

[0021] Furthermore, the top surface of the gripping lifting plate 26 is fixed with multiple vertical guide rods, which are inserted into guide through holes formed on the gripping connecting plate 24 and cooperate with the guide through holes.

[0022] Furthermore, connecting blocks are fixed to the front and rear of the top surface of the right side of the horizontal fixed plate 12, and a first proximity switch 1 is fixed on each connecting block. The sensing end of the first proximity switch 1 corresponds to the sensing block 211 fixed on the right side wall of the moving block 21.

[0023] Furthermore, a bottom fixing plate 111 is fixed to the top of the output shaft of the main rotary servo motor 11, and a horizontal fixing plate 12 is fixed to the top surface of the bottom fixing plate 111. The bottom fixing plate 111 is a circular plate, and its central axis coincides with the central axis of the output shaft of the main rotary servo motor 11. The bottom left, right and front bottom surfaces of the bottom fixing plate 111 are all fixed with lower sensing protrusions 2. The top surface of the horizontal fixing plate 12, which is directly below the lower sensing protrusions 2 at the front, is fixed with a second proximity switch 3. The sensing end of the upper end of the second proximity switch 3 corresponds to the three lower sensing protrusions 2.

[0024] Furthermore, a connecting frame is fixed on the top surface of the top plate of the feeding rack 30 at the front right end of the placing block 31, and a third proximity switch 4 is fixed on the connecting frame. The sensing end of the third proximity switch 4 corresponds to the third sensing block 5 fixed on the left side wall of the vertical fixing plate 23.

[0025] In this embodiment, all electrical components are electrically connected to the control host via electrical connection lines and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0026] In this embodiment, during use, the preceding equipment places two workpieces 100 (plates) to be processed into the feeding groove 32 at the placement block 31, with their outer sidewalls tightly against the inner sidewalls of the feeding groove 32. Then, the control host controls the main rotation servo motor 11 to run. When the lower sensing protrusion 2 on the left side is sensed by the sensing end of the upper end of the second proximity switch 3, it indicates that it has rotated to the correct position. At this time, the moving motor 281 runs, moving the gripping lifting plate 26 to the left until the third sensing block 5 is sensed by the third proximity switch. 4. Once the sensor detects the workpiece, it indicates that the workpiece has moved into position. At this point, the gripping lifting plate 26 is directly above the two workpieces 100. The lifting cylinder 25 pushes the corresponding vacuum suction cup 200 against the top surface of the corresponding workpiece 100, adsorbing the workpiece 100. Then, the lifting cylinder 25 retracts, lifting the workpiece 100 and removing it from the corresponding feeding groove 32 (in this embodiment, the bottom surface of the feeding groove 32 and the top surface of the heating placement plate on the base plate of the dual-station CNC hot press are formed into two...). The bottom surfaces of the placement grooves are on the same plane to ensure normal gripping. Then, the extension rod 22 is retracted by the operation of the moving motor 281 until the first proximity switch 1 at the front senses the sensing block 211 of the moving block 21, indicating that it has returned to the correct position. Then, the main rotary servo motor 11 is run so that the lower sensing protrusion 2 at the front is sensed by the sensing end of the upper end of the second proximity switch 3, indicating that it has moved to the correct position. At this time, the moving motor 281 is run to grip the lifting plate 26 to move backward until the first proximity switch 1 at the rear senses the sensing block 211 of the moving block 21, indicating that it has moved to the correct position. At this time, the workpiece 100 is directly above the corresponding placement groove formed on the top surface of the heating placement plate on the base plate of the dual-station CNC hot press. Then, the push rod of the lifting cylinder 25 is pushed so that the workpiece 100 is placed in the corresponding placement groove, with its bottom surface pressing against the bottom surface of the corresponding placement groove. The outer side wall of the workpiece 100 is close to (with a gap of 1 to 2 mm) or tightly attached to the inner side wall of the corresponding placement groove.

[0027] Then, the vacuum suction cup 200 stops suctioning, the push rod of the lifting cylinder 25 retracts, the moving motor 281 runs, the lifting plate 26 is gripped and moved forward, and then returns to its original position. Then, the dual-station CNC hot press can perform hot pressing processing. After processing is completed, the moving motor 281 runs, and the first proximity switch 1 at the rear senses the sensing block 211 of the moving block 21, indicating that it has moved into position. Then, the vacuum suction cup 200 is activated by the push rod of the lifting cylinder 25 to adsorb and fix the processed workpiece 100. Then, the push rod of the lifting cylinder 25 retracts, the moving motor 281 runs, the lifting plate 26 is gripped and moved forward, and then returns to its original position.

[0028] Then, the main rotary servo motor 11 is operated, so that the lower sensing protrusion 2 on the right side is sensed by the sensing end of the upper end of the second proximity switch 3, indicating that the rotation is in place. At this time, the adsorbed workpiece 100 is above the workpiece conveying frame 40. The workpiece 100 is pushed by the push rod of the lifting cylinder 25 to approach the top surface of the conveying roller of the workpiece conveying frame 40 (the workpiece conveying frame 40 in this embodiment is a simplified schematic diagram). Then, the vacuum suction cup 200 is closed, and the workpiece 100 is on the corresponding conveying roller. By running the workpiece conveying frame 40, it can be conveyed to the subsequent equipment, and the processing effect is good.

[0029] In this embodiment, the workpiece conveyor 40 can be a through roller conveyor or the conveyor roller can be replaced with an electric conveyor roller. The workpiece 100 on it can continue to be conveyed to the right by the electric conveyor roller.
